# AmpStamp vs Cab ML

The clearest difference is rating: AmpStamp at 4.4 against Cab ML's 4.0. AmpStamp also leads on ratings volume (32 vs 4). Cab ML's advantage is update cadence (every 3 weeks vs every 6 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. AmpStamp sells 10 in-app purchases, starting at $4.99 per month and Cab ML sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AmpStamp holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: AmpStamp has 32 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 55% of AmpStamp's written reviews are positive against 50% of Cab ML's.

AmpStamp ships an update every 6 weeks, Cab ML every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
